Task Manipulation Effects On The Relationship Between Working Memory Capacity And Go/No-Go Performance, Elizabeth A. Wiemers
Task Manipulation Effects On The Relationship Between Working Memory Capacity And Go/No-Go Performance, Elizabeth A. Wiemers
Open Access Theses
Seemingly minor task manipulations can have large and sometimes unpredicted effects on task performance. Despite this, single tasks are typical in both research and assessment applications. This series of experiments aims to systematically investigate the differences between various perceptual and semantic versions of go/no-go tasks and their relationships with working memory capacity (WMC) with the goal of determining the cause of inconsistencies in the literature. Because these versions of the go/no-go have not previously been systematically studied, the first experiment does so. After determining which performance differences exist based on versions of both task and decision, and noting that these …
Enhancing Travel Experience With The Combination Of Information Visualization, Situation Awareness, And Distributed Cognition, Weiran Lei
Open Access Theses
With the new forms of travel introduced by new technologies of transportation and communication, a satisfied travel experience could be affected by various factors before and during a trip. Especially for road trips, traveling by car provides freedom on time control while leading to more possibilities of rescheduling initial plans made under time constraints. When overwhelmed with the need for changed travel context to avoid unexpected events that will require a serious change of initial plans, travelers need to find and access helpful contextual information quickly. This is a context-related decision making process that requires amplifying human situation awareness and …
Customer Envy At Service Encounters, Gerardo Anaya
Customer Envy At Service Encounters, Gerardo Anaya
Open Access Theses
Envy has been regarded as a complex emotion which can produce both positive and negative outcomes for consumers. This study explored the subjective experience of customer envy at service encounters in order to better understand how customers respond to unflattering comparisons with an envied customer. A questionnaire was designed to measure the cognitive appraisals, emotional responses, and consequences of customer envy. Study participants were also asked to share their envy incidents in the survey. A sample of 300 participants was collected and used for analysis. The findings illustrate that distinctively different patterns of cognitive appraisals such as preferential treatment, are …
Optimization Of Switch Virtual Keyboard By Using Computational Modelling, Xiao Zhang
Optimization Of Switch Virtual Keyboard By Using Computational Modelling, Xiao Zhang
Open Access Theses
In this thesis, I first reviewed some keyboard technologies used by people with motor difficulties, and described design elements that influence efficiency. I cast the design of a switch keyboard as an optimization problem, and arrangement of keys on such a keyboard as a Mixed Integer Programming problem. One significant variable in the MIP problem, the error rate, is related to several other variables. I treated modeling of the error rate as a parameter estimation problem, and used a data mining method. I designed HCI experiments to gather data for parameter estimation, using Bayesian logistic regression model. The empirical data …
Preschoolers’ Physical, Social, And Engineering Play Behaviors: Differences In Gender And Play Environment, Zachary S. Gold
Preschoolers’ Physical, Social, And Engineering Play Behaviors: Differences In Gender And Play Environment, Zachary S. Gold
Open Access Theses
This study explored gender differences in the occurrence of 66 preschoolers' (ages 3-to-5; 29 girls, 37 boys) physical, social, and "engineering thinking play" behaviors across three play environments: the traditional playground, the dramatic play area, and an environment in which children played with large, manipulable, loose parts. Previous research has indicated that young children are not engaging in enough physical play to maintain healthy lifestyles. Play may also have benefits for social competency and cognitive development. Observations of children's engagement with a new and engaging play material, Imagination Playground TM blocks, which are designed to foster imaginative and creative constructive …
A Rat Model Of Mild Blast-Induced Head Trauma With Structural And Biochemical Abnormalities In The Absence Of Motor Deficits, Michael Kelso Walls
A Rat Model Of Mild Blast-Induced Head Trauma With Structural And Biochemical Abnormalities In The Absence Of Motor Deficits, Michael Kelso Walls
Open Access Theses
Blast injury has been coined the "signature injury of the Iraq war" resulting in a surge of interest in understanding and addressing the corresponding pathological sequelae. As modern warfare develops into a distinctly guerrilla style combat by smaller terrorist groups against larger, regimented forces, tactics like suicide bombing and roadside bombing with Improvised Explosive Devices (IEDs) become more prevalent. 1,2 This increased use of IEDs countered with improved body armor and protective technologies has significantly increased the survival rate of such attacks. 1.2 However, as survival rates have improved with body armor and other protective technologies, the incidence of reported …
